board: adi: Add support for SC598

This adds support for the Analog Devices SC598-SOM and configurations
for using it with both the SOMCRR-EZKIT and SOMCRR-EZLITE. This adds
dtsis for both Rev D (including older revisions) and Rev E SOMs, which
are not compatible due to BOM changes. Although no new Rev D SOMs are
produced as of 2025, many are in circulation, so the RevD dtsi is
included to facilitate use for existing customers.
